Hello,
i drop my km4a1 and some pieces are broken.
I try to remove the barrel nut, that is under the delta ring, from the outer barrel, but no succes.
I find allmost all i need to bring back to life my kwa, but not the barrel nut.
In parts diagram is number 269.
A link, a clue to find this?
Thanks In advance.

You can call KWA and order one over the phone, They will ship internationally. Or, and this probably makes more sense if you are in Bucharest, look on sites like eHobbyAsia, WGC, Uncompany, and Tokyo Model Company. You can order online and ship worldwide.

Thanks gcw360.
i sent an email to kwa.
If you or anybody can help me to solve some problems of compatibility. i search on this forum, but i'm not satisfied.
My outer barrel, inner barrel and upper receiver are broken.
Inner barrel i want to buy from kwa store or find some 6.05/6.04 barrel
Outer barrel and upper receiver for an ordinary m4 are compatible with kwa m4?
i mean something like this:

Needless to say the parts from KWA are drop in replacements. An outer barrel replacement that is good is any of the Madbull barrels. The upper receiver needs to be KWA. There are no after market, non-KWA uppers that will fit.
